Error Diffusion screens photographic areas of a document to
simulate gray levels yet sharpens the edges of text. It is recommended
that error diffusion be used when a mix of text, graphs, pictures and
colors in the documents are being scanned.
NOTE: When using error diffusion and compression together, negative
compression (less than one-to-one) is more likely to occur.
Dithering a method used to simulate gray levels. The following
Dither options are available:
64-Level Bayer Dither, 64-Level 45 Degree Clustered Dot
